//! \brief Geometric data cache.
/*!
MGeometry stores the collection of MGeometryData arrays which describe
a Maya surface, including per-component data such as UV mapping and colour.

Various methods are provided for returning MGeometryData containing the
data for different properties of the geometry: the position() method
returns position data, the normal() method returns normals, and so on.

The primitiveArray() method returns MGeometryPrimitive's which provide
indexing into those property arrays for each primitive to be drawn.
